Application May 13, 194s, serial No. 669,387

This invention relates to swimming pools, and particularly to a swimming pool construction of a portable nature, since it is easily assembled and dismantled for removal from one location to another with the minimum of effort and time.

Small swimming pools, constructed from waterproof canvas or rubberized material, are known,` such pools having the canvas fastened to an upper frame-work and resting either on a floor or on the ground. The present invention is v.directed to a full sized type of swimming pool which may be used on school playgrounds or for made Yof light material, such as aluminum, andl may be thus easily handled and transported. Specialy reinforcing is constructed into each section.

Y The principal object of the invention, therefore, is. to provide an improved swimming pool construction.

Another'object of the invention is to provide an improved swimming pool which may be .quickly assembled and dismantled and imoved from one location to another.

A further object of the invention is to provide an improved portable swimming pool of normal size suitable for schoolgrounds and theatrical performances. Y

A still further object of the invention is to provide a swimming pool of sections'having water tight interlocking joints which may be quickly dismantled and reassembled.

Although the novel features which are believed to` be characteristic of this Yinvention will be pointed out with particularity in the appended claims, the manner of its organization and the mode of its operation will be better understood by referring to the following description read in conjunction with the accompanying drawings, forming a part hereof, in which:

Fig. 1 is a plan view of a portable swimming pool embodying the invention.

Fig. 2 is a side elevational View `of the swimming pool asshown in Fig. 1.

6 Claims. (Cl. 1 -172) Fig. 3 is a cross-sectional view at one end of the swimming pool.

Fig. 4 is a cross-sectional end View oi the swimming pool showing the bracing of the side members.

Figs. 5 and 6 are detail views showing the interlocking arrangement of the side and bottom sections of the pool taken along the lines 5-5 and respectively, of Fig. 4.

Fig. '7 is a perspective exploded view showing the manner in which the sections are arranged for assembly.

Fig. 8 is a plan view of the intersection of four bottom sections of the pool.

Figs. 9 and 10 are detailed cross-sectional views showing the manner of interlocking the corners rof the bottom sections of the pool and taken along the lines 9--9 and lil-l0, respectively, of Fig. 8, and

Fig. ll is a cross-sectional, detail view of the glass panel at one end of the pool taken along vthe line II-ll of Fig. 1.

Referring now to the drawings, in which the same numerals identify like elements, and referring particularly to Figs. l and 2, the pool is rectangular in shape and made up of interme* lis to be understood that locker space, dressing serted inthe sections of the tank with the properY brass and rubber water-tight ttings shown at 23 andri. lnlet andoutlet holes :may be provided at` Zand 2i, respectively, an additional opening being shown at 23 in Fig. 7 for the pur- -pose of completely draining the tank. Between openings 26 and 2l, a circulatory system may be 55 provided for recirculating the water from the outlet 21 back into the inlet 26 through any suitable lter arrangement.

Referring now to the specific construction of the pool, as mentioned above, it is made up of four different types of sections; that is, bottom, bottom-corner, side, and side-corner sections. Referring now to Fig. '7 two bottom sections are shown at 32 and 33 and two bottom-corner sections are shown at 30 and 3|. Although all sections could be made of wood, plastic, and steel, sheet aluminum is preferred, because of its lightness and ease of fabrication. Bottom sectionsg and 33 are f'lat with upturned ends at right angles to the bottom portions. The corner-bottom sections have upturned ends and sides with rounded corners, as shown at 35, formed by the bottom surface and the upturned portions. The corners may be formed and then welded. Flanges 29 and 38 extend outwardly from the bottom and bottom-corner sections, these flanges being drilled withholesv approximately six inches apart to receive the fastening bolts. Referring specically to corner-section 3|, it will be noted that the inner edges have a step-back portion 31 which extends completely around the inner edges of the section and up the upturned portions. vAt the inner corner 46 of section 3|, there is a double step-back to form a water-tight joint between the four `.sections 30, 3|, 32, and 33, as shown in Figs. 8, 9and-10.

Section 3|) is similar to corner section 3|, except that it has a step-back 4| only on one of the inner edges of the section. Section 32 has a stepback edge 42 similarly-to edge 4| of section 30, while section 33 has a step-back end edge 44 and a step-backv side 45 with the corner 46 having a double step-back similarly to corner 40. Each of these sections'is provided with stiffening ribs, as shown at 41, 46, and 49.

'Referringnowto' Figs. 8, 9, and 10, the sections 3 3, 3|, 32,\and 33 are shown interlocked, Fig. 8

being a plan view and Figs. 9 and 10, cross-sectional views taken at right angles at the corner. This interlocking Varrangement is important, since it permits a non-leakable pool to be quickly dismantled andre-assembled. To insure a watertight condition, the adjacentoverlapping surfaces of double step-backs 40 and 46 at the corners and along the sides are separated by strips of ,#6 inch Johns-Manville No. 60 service lsheet packing. With this packing between the joints, the sections are then bolted together, pref- .erably with 1A; inch bolts 36 spaced approximately six inches between centers. (See Fig. 5.) As mentioned above, it has been found that although Wood, plastics, or steel could be used for the Sections, sheet aluminum is preferred, the

,aluminum being treated with Alrok followed by .-a zinc chlorinate primer and then baked enamel to prevent the aluminum from being affected by .the chlorine in the Water.

After `the bottom Vsections are bolted together, the side-corner sections, such as and 52, are then bolted to the bottom sections 30 and 3| respectively, these sections having the curvature of the corners of the bottom sections and being provided with flanges on the bottom and sides. The No. 60 packing is also used between the flanges, as shown at 34 in Figs. 5 and 6. The upper edges of all side and side-corner sections have overhanging or rolled edges, such as shown at 54, '51, and 58, to provide additional strength.

`After the Vcorner sections have been bolted in place, the side sections 55 and 56, having drilled danses along their bottom, andside edges. may

4 then be bolted to the corner sections 5| and 52 and to the bottom sections, the above-mentioned Johns-Manville packing being used between the flanges. The complete pool, therefore, is thus assembled.

The above design of the swimming pool is such that it may be easily and quickly dismantled and assembled by a minimum number of men, such as two, and is durable and rugged enough to stand rough treatment. Since the tank sections are of sheet aluminum, such as GIS-W, the bottom is sufliciently flexible to conform to an uneven surface, thus permitting the pool to be erected on rough-ground. It is realized that the sections of the pool may be made in various sizes, and when large sized pools are constructed, the side members, such as y56, could be supported by outrigger bracing, such as shown at 62 and 62 in Fig. 4. The size of the bottom sections may be tion, andto prevent theloss of bolts, the bolts 36 may be welded to strips, thereby permitting as many as twelve bolts to be positioned with the same motion. .All iron and braces are galvanized to avoid any rust and possible electrolytic action between thealuminum and other metals.

Another feature of the tank is the provision of a scum or over-flow gutter, such as is shown at 63in Fig. 3. This gutter may be suspended and adjustable on a strip 64 hung over the rolled edge '58 of the upper end corner and side members. The gutter may have an inclination toward one corner and a drain provided which will pass outthrough flexible tubing through a hole in the side of the tank. The hand rail I8 encircles the deck and may be arranged to be easily set on the post studs I0 and fastened firmly in place in any suitable manner. The ladders may be simplyhooked onto the deck members. Furthermore, in the circulatory filter system, a heater may be added, if desired, in order to provide the desired temperature.
